Thank you! I've adjusted your commit log slightly. The "tiny change" note indicates that your diff is small enough that you do not have to assign copyright. I have also made minor wording changes, added the standard ChangeLog-style filename (function) lines and added the obligatory bug-fix reference in NEWS. We could add a test for this and even label it "expensive" or "very-expensive", but so far I don't think it's worthwhile. Will push the attached tomorrow.
